Abstract: A redundant device unit includes a first device connected with a field device via a first link and a second link in series. The first device, initially active in use, when active sends diagnostic information indicating whether there is a fault in the first link and/or the second link. A second device connected with the field device via the second link and a third link in series, initially passive in use, receives the first diagnostic information from the first device. When the first diagnostic information indicates that there is a fault in the first link and/or the second link, the first device switches to passive and the second device switches to active and generates second diagnostic information indicating whether there is a fault in the second link and/or the third link. A determination regarding the fault is made based on the first and second diagnostic information.

Abstract: Embodiments of the present invention disclose a circuit structure and a method for reducing power consumption of a device including an active module and a passive module. The circuit structure comprises: an active module (22) comprising a main output voltage (221) for powering a load (26) via a first current control device (222) which is configured to control a current passing through the load (26), and an passive module (24) comprising a main output voltage (241) for when the active module (22) fails, powering the load (26) via a second current control device (242) which is configured to control a current passing through the load (26). The passive module (24) further comprises an auxiliary output voltage (243) for when the passive module (24) is in a backup state, powering the second current control device (242) so as to enable the second current control device (242) to be in a switching-on state. Further, the auxiliary output voltage (243) of the passive module (24) is configured to be smaller than the main output voltage (241) of the passive module (24).

Abstract: A module has switchable operation states. A first switching unit switches the module between a first operation state and a second operation state. A first interface switches between sending signals to another module which has switchable operation states and receiving signals from the other module. The first interface sends a first signal to the other module when the module is in the first operation state, sends a second signal to the other module when the module is to be switched into the second operation state, and receives signals from the other module when the module is in the second operation state. A second interface communicates with the other module. When the second interface receives a response of the other module to the second signal, the first switching unit switches the module into the second operation state. The reliability of module switching is improved in an embodiment.
